Tool for Semiautomatic Labeling of Moving Objects in Video Sequences: TSLAB

open access: yesSensors, 2015
An advanced and user-friendly tool for fast labeling of moving objects captured with surveillance sensors is proposed, which is available to the public. This tool allows the creation of three kinds of labels: moving objects, shadows and occlusions. These

Evaluating the Effects of Shadow Detection on QuickBird Image Classification and Spectroradiometric Restoration

open access: yesRemote Sensing, 2013
Shadows in high resolution imagery create significant problems for urban land cover classification and environmental application. We first investigated whether shadows were intrinsically different and hypothetically possible to separate from each other ...

Use of the SAR Shadowing Effect for Deforestation Detection with Sentinel-1 Time Series

open access: yesRemote Sensing, 2018
To detect deforestation using Earth Observation (EO) data, widely used methods are based on the detection of temporal changes in the EO measurements within the deforested patches. In this paper, we introduce a new indicator of deforestation obtained from

Shadow Images of a Rotating Dyonic Black Hole with a Global Monopole Surrounded by Perfect Fluid

open access: yesUniverse, 2020
In this paper, we revisit the rotating global monopole metric and extend the metric to a rotating dyonic global monopole in the presence of a perfect fluid. We then show that the surface topology at the event horizon, related to the metric computed, is a

Shadow-Based Hierarchical Matching for the Automatic Registration of Airborne LiDAR Data and Space Imagery

open access: yesRemote Sensing, 2016
The automatic registration of LiDAR data and optical images, which are heterogeneous data sources, has been a major research challenge in recent years. In this paper, a novel hierarchical method is proposed in which the least amount of interaction of a ...
